At Schreiber, our focus is simple: We improve wastewater. How we do it is pure ingenuity. With installations at more than 2,000 water treatment facilities worldwide, Schreiber has provided unique design (over 25 patents, from screw pumps to tertiary filtration), outstanding fit and finish, on-site expertise and responsive service since 1979. Technological innovations—such as the compressible Fuzzy Filter media system and the Continuously Sequencing Reactor (CSReactor)—have greatly improved cost effectiveness and energy efficiency in wastewater treatment and continue to identify Schreiber as a leader in the industry.

Schreiber's continuously sequencing reactor (CSR) is a biological nutrient removal system that sequences through aerobic, anoxic and anaerobic phases in a single basin. The design allows complete separation of aeration and mixing with 100% aeration turndown capability, allowing the aeration to be turned off while the CSR applies low-energy mixing without adding air. more

The Fuzzy Filter is a compressible media filter for water and wastewater treatment systems. Operating in an upflow or downflow design, it achieves a high rate of solids removal through the use of synthetic fiber spheres. With loading rates of 40-plus gpm per square foot, the filter requires 20% of the space of sand filters. Applications include tertiary wastewater, prefiltration for RO systems,... more

The Fuzzy Filter is a cost-effective synthetic compressible media filter. With loading rates of 30 to 40-plus gpm per sq ft, the filter requires 20% of the space for sand filters. Applications include tertiary wastewater treatment, influent river water, pre-RO water cleansing, contaminated storm water, membrane backwash water and cooling water side-stream filtration. more

Schreiber’s Grit & Grease Removal System consists of a rectangular concrete channel with two parallel chambers. The rectangular design provides efficient removal over a wide range of flows. One chamber is for the settling of grit and the other floats grease to the surface for removal. In the grit channel, coarse bubble diffusers create a continuous and adjustable roll. In the grease channel,... more

Schreiber offers both open flight (OFSP) and tube-mounted (TMSP) screw pumps. The OFSP transports liquid in a concrete trough. It is a non-clog pump, typically installed at a 30- or 38-degree angle, and it has a variable capacity at a constant speed up to its maximum. The TMSP transports liquid inside a stationary tube, simplifying design and eliminating the need for grouting. Both types of screw... more

Schreiber’s front-loader bar screen completely removes screenings and places them into a container for disposal. The rake engages the bars of the screen at the bottom of the channel from the downstream side to prevent jamming. A float switch and timer control its automatic operation. more

Schreiber’s fine screen is composed of a stationary grid and a movable grid consisting of parallel SS bars with a step configuration. The bars of the movable grid are between the bars of the stationary grid in an alternating fashion; screenings are conveyed upward in a stepwise manner along the stationary grid, resulting in a back-cleaning system that prevents screenings by being forced through... more

Schreiber’s MC fine screen is a traveling band, deep-channel screen with depths of up to 50 in. and widths of up to 14 in., without the need for a center chain and with slot spacing to 1 mm. The block design is mounted to the drive chain without interconnection to other blocks, thus minimizing wear and allowing for easy element replacement. It is custom-configurable and easy to maintain. more

One chamber is for the settling of grit, and the other floats grease to the surface for removal. In the grit channel, coarse bubble diffusers create a continuous and adjustable roll; in the grease channel, floatables are continuously transported to the end of the channel by an air/... more

Schreiber’s peripheral drive clarifiers utilize leverage rather than center-drive torque to rotate the scraper and skimming assembly. Equipment for the removal of floatables and settled solids is suspended from a rotating bridge. Rotating skimming equipment removes floatables regardless of wind direction, and helical scrapers transport settled solids to the center of the basin in a single... more

Schreiber’s Fuzzy Filter is an innovative and cost-effective compressible media filter that achieves an exceptionally high rate of solids removal through the use of synthetic fiber spheres. With loading rates of more than 40 gpm per sq ft, it is compact and modular, and it can be used for a wide variety of applications, including tertiary WW, phosphorus removal prefiltration to RO systems, water... more

Combined sewer overflow (CSO) and sanitary sewer overflow (SSO) applications are characterized by high flows and dramatic variations in solids loading; solids removal is the key to successful treatment. With unsurpassed hydraulic loading capacity and high solids storage, Schreiber’s compressible media filter—the Fuzzy Filter—is proven in CSO/SSO applications, such as the 85 mgd West Area plant... more

Schreiber’s Fuzzy Filter is a unique high-rate compressible media filter with a small footprint—it requires 20% of the space that sand filters use.

Applications include tertiary wastewater treatment, influent river water, Pre-RO water cleansing, contaminated storm water,... more

The Fuzzy Filter is a synthetic compressible media filter that requires 80% less space than the typical sand filter. It is Title 22-accepted at 40 gpm per sq ft, and it has been utilized for water reuse applications across the nation, producing 2-ntu or better effluent.
